Regrouting Shower Tile (7 Steps, Pro Video!)

You’re not alone!

One of the most common mistakes I see homeowners make is diving headfirst into regrouting their shower tiles without a solid plan.

It’s like trying to bake a cake without a recipe – you might get something edible, but chances are it’ll be a mess!

Rushing the process, skipping prep work, or grabbing the wrong materials can lead to a finish that’s, well, less than perfect.

I’ve seen it all: grout that cracks within weeks, colors that clash, and even water damage that could have been avoided.

Trust me, I’ve been there too.

Back in my early days as a contractor, I once used the wrong type of grout on a delicate mosaic tile and the result?

Let’s just say it involved a lot of extra elbow grease and a very understanding client.

The key is to take your time, do your research, and approach regrouting with a bit of patience and a whole lot of know-how.

In this article, I’m going to walk you through the entire process, step by step, so you can achieve a professional-looking finish that will transform your shower and protect your home from water damage.

Ready to get started? Let’s dive in!

Section 1: Understanding the Importance of Regrouting

Okay, let’s get down to brass tacks: what exactly is regrouting, and why should you even bother?

Regrouting is simply the process of removing the old, damaged grout between your tiles and replacing it with fresh, new grout.

Think of grout as the glue that holds your tiled masterpiece together.

It fills the gaps between the tiles, preventing water from seeping behind them and causing all sorts of problems.

So, how do you know it’s time to regrout?

Here are a few telltale signs:

• Mold growth: Those unsightly black or green spots are a major red flag.
  
  Mold thrives in damp environments, and if it’s growing in your grout, it means water is getting in.
• Cracked or crumbling grout: If your grout is cracked, chipped, or falling apart, it’s no longer doing its job.
  
  Water can easily penetrate through these cracks and cause damage.
• Water leakage: This is the most serious sign.
  
  If you notice water leaking through your shower walls or floor, it’s crucial to address the problem immediately.
  
  Regrouting can often solve the issue, but you may also need to address underlying structural damage.

I remember one time, a client called me in a panic because their downstairs ceiling was leaking.

Turns out, the shower grout upstairs had completely failed, and water was seeping through the floor and into the ceiling below.

A simple regrouting job turned into a major repair because they had waited too long to address the problem.

Benefits of Regrouting

So, why go through the hassle of regrouting? Here are a few key benefits:

• Improved appearance: Fresh grout can instantly transform the look of your shower.
  
  It can brighten up the space and make it look cleaner and more inviting.
• Enhanced water resistance: New grout creates a watertight seal, preventing water from penetrating behind the tiles and causing damage.
  
  This can save you money on costly repairs down the road.
• Increased longevity of the tiles: By protecting the tiles from water damage, regrouting can help extend their lifespan.
  
  This means you won’t have to replace your tiles as often, saving you even more money.

According to the National Kitchen and Bath Association (NKBA), a well-maintained bathroom can increase the value of your home by as much as 10%.

Regrouting is a relatively inexpensive way to improve the look and functionality of your bathroom, making it a worthwhile investment.

Section 2: Tools and Materials Needed

Alright, let’s talk tools.

Having the right equipment is half the battle.

Here’s what you’ll need to tackle your regrouting project:

• Grout removal tool or oscillating tool: This is essential for removing the old grout.
  
  I personally prefer an oscillating tool with a grout removal blade, as it’s faster and more efficient.
  
  However, a manual grout removal tool will also work, especially for smaller areas.
• New grout: This is the star of the show!
  
  We’ll talk more about the different types of grout in the next section, but for now, just make sure you choose a grout that’s appropriate for your tile type and the width of your grout lines.
• Grout float: This is a rubber-faced tool used to press the grout into the joints between the tiles.
• Sponge and bucket: You’ll need these to clean up excess grout from the tile surface.
• Caulk: Use caulk to seal the corners and edges of your shower, where the walls meet the floor or ceiling.
  
  This will help prevent water from seeping behind the tiles in these vulnerable areas.
• Safety goggles and gloves: Protect your eyes and hands from dust, debris, and harsh chemicals.

Here’s a more detailed breakdown:

A few extra tips:

• Invest in quality tools: Cheap tools can break easily and make the job more difficult.
  
  It’s worth spending a little extra money on tools that will last.
• Read the instructions: Always read the manufacturer’s instructions for all of your tools and materials.
  
  This will help you use them correctly and avoid any potential problems.
• Don’t be afraid to ask for help: If you’re not sure about something, don’t hesitate to ask a professional for advice.
  
  A little guidance can go a long way.

Section 3: Preparing the Shower Area

Preparation is key to a successful regrouting project.

Before you even think about touching that grout, you need to make sure your shower area is clean, dry, and ready to go.

Step 1: Clean the Shower Surface

Start by giving your shower a thorough cleaning.

Remove all soap scum, mildew, and dirt.

I recommend using a good quality bathroom cleaner that is specifically designed to remove these types of stains.

You can also use a homemade solution of vinegar and water.

Mix equal parts vinegar and water in a spray bottle, spray it on the shower surface, and let it sit for a few minutes before scrubbing it clean.

Pro Tip: For stubborn stains, try using a scrub brush with stiff bristles.

This will help you get into the grout lines and remove any built-up grime.

Step 2: Assess the Existing Grout

Once the shower is clean, take a close look at the existing grout.

Identify areas that need regrouting.

Look for cracks, chips, mold, and other signs of damage.

It’s also important to check for any underlying issues, such as water damage.

If you notice any soft spots or discoloration in the surrounding walls or floor, it could be a sign of a more serious problem.

In this case, it’s best to call a professional to assess the damage and make any necessary repairs before you start regrouting.

Step 3: Remove Old Grout

Now comes the fun part: removing the old grout!

This can be a bit time-consuming, but it’s essential to remove all of the old grout before you apply the new grout.

Here’s how to do it:

1. Choose your tool: As I mentioned earlier, you can use a manual grout removal tool or an oscillating tool with a grout removal blade.
   
   I prefer the oscillating tool, as it’s faster and more efficient.
2. Protect yourself: Put on your safety goggles and gloves.
3. Start removing the grout: If you’re using an oscillating tool, hold it at a slight angle to the grout line and gently guide it along the grout, being careful not to damage the surrounding tiles.
   
   If you’re using a manual grout removal tool, simply scrape the grout out of the joints.
4. Clean up the dust: As you remove the grout, it will create a lot of dust.
   
   Use a vacuum cleaner or a damp cloth to clean up the dust as you go.
5. Remove all of the old grout: Make sure you remove all of the old grout from the joints.
   
   This will ensure that the new grout adheres properly.

Important Note: Be careful not to damage the tiles when removing the grout.

Work slowly and carefully, and don’t apply too much pressure.

I once had a client who tried to rush the grout removal process and ended up chipping several of their tiles.

It was a costly mistake that could have been avoided by taking a little more time and care.

Section 4: Choosing the Right Grout

Okay, so you’ve prepped your shower and removed the old grout.

Now it’s time to choose the right grout for your project.

There are several different types of grout available on the market, each with its own unique properties and benefits.

Here’s a quick rundown:

Sanded vs. Unsanded Grout

• Sanded grout: This type of grout contains sand, which makes it stronger and more durable.
  
  It’s typically used for grout lines that are 1/8 inch wide or wider.
• Unsanded grout: This type of grout does not contain sand, which makes it smoother and easier to work with.
  
  It’s typically used for grout lines that are less than 1/8 inch wide.

The sand in sanded grout helps to prevent it from shrinking and cracking, making it a good choice for larger grout lines.

Unsanded grout, on the other hand, is more flexible and less likely to scratch delicate tiles.

Epoxy Grout

Epoxy grout is a two-part grout that is made from epoxy resins and a hardener.

It’s incredibly durable, stain-resistant, and waterproof, making it an excellent choice for showers and other wet areas.

Epoxy grout is also more expensive than sanded or unsanded grout, and it can be more difficult to work with.

However, its superior performance makes it well worth the investment for many homeowners.

Factors to Consider

When choosing grout, here are a few factors to keep in mind:

• Tile type: Some tiles are more delicate than others.
  
  If you’re working with glass, ceramic, or other delicate tiles, you’ll want to use unsanded grout to avoid scratching them.
• Spacing: The width of your grout lines will determine whether you need sanded or unsanded grout.
• Exposure to moisture: If your shower is heavily used or prone to moisture, you’ll want to choose a grout that is waterproof and resistant to mold and mildew.

Color Selection

The color of your grout can have a big impact on the overall look of your shower.

You can choose a grout color that matches your tiles for a seamless look, or you can choose a contrasting color to create a more dramatic effect.

Here are a few tips for choosing grout colors:

• Consider the color of your tiles: If you have light-colored tiles, you may want to choose a light-colored grout to create a bright and airy look.
  
  If you have dark-colored tiles, you may want to choose a dark-colored grout to create a more dramatic effect.
• Think about the overall style of your bathroom: If you have a modern bathroom, you may want to choose a neutral grout color, such as gray or white.
  
  If you have a more traditional bathroom, you may want to choose a warmer grout color, such as beige or brown.
• Test the grout color before you apply it: Before you apply the grout to your entire shower, test it in a small, inconspicuous area to make sure you like the color.

I once had a client who chose a bright red grout for their shower.

While it was certainly a bold choice, it didn’t quite match the overall style of their bathroom.

In the end, they decided to go with a more neutral grout color, which looked much better.

Section 5: The Regrouting Process

Alright, you’ve prepped the shower, removed the old grout, and chosen the right grout for the job.

Now it’s time to get down to the actual regrouting process.

Step 4: Mixing the Grout

Start by mixing the grout according to the manufacturer’s instructions.

This is a crucial step, as the consistency of the grout will affect how easy it is to apply and how well it adheres to the tiles.

Here are a few tips for mixing grout:

• Use a clean bucket: Make sure your bucket is clean and free of any debris.
• Add water gradually: Add water to the grout powder gradually, mixing constantly until you achieve the desired consistency.
  
  The grout should be thick and creamy, like peanut butter.
• Don’t overmix: Overmixing the grout can cause it to become too thin and runny.
• Let it sit: After you’ve mixed the grout, let it sit for a few minutes to allow the ingredients to fully combine.

Step 5: Applying the New Grout

Using a grout float, apply the new grout to the joints between the tiles.

Hold the float at a 45-degree angle to the tiles and press the grout firmly into the joints.

Make sure you fill all of the joints completely, and remove any excess grout from the tile surface as you go.

Here are a few tips for applying grout:

• Work in small sections: Don’t try to grout the entire shower at once.
  
  Work in small sections, about 2-3 square feet at a time.
• Use a firm, even pressure: Apply a firm, even pressure to the grout float as you move it across the tiles.
  
  This will help ensure that the grout is packed tightly into the joints.
• Remove excess grout immediately: Use the edge of the grout float to scrape off any excess grout from the tile surface.

Step 6: Cleaning Excess Grout

After you’ve applied the grout to a section of the shower, use a damp sponge to clean off any excess grout from the tile surface.

Rinse the sponge frequently in a bucket of clean water, and wring it out thoroughly before wiping the tiles.

Here are a few tips for cleaning grout:

• Use a clean sponge: Make sure your sponge is clean and free of any debris.
• Wring out the sponge thoroughly: A wet sponge can leave streaks on the tile surface.
• Change the water frequently: As you clean the tiles, the water in your bucket will become dirty.
  
  Change the water frequently to avoid smearing the grout.

Step 7: Sealing the Grout

After the grout has dried completely, apply a grout sealer to protect it from stains and water damage.

Follow the manufacturer’s instructions for applying the sealer.

Typically, you’ll apply the sealer with a brush or a sponge, and let it sit for a few minutes before wiping off any excess.

Here are a few tips for sealing grout:

• Use a high-quality sealer: Choose a grout sealer that is specifically designed for use in showers.
• Apply the sealer evenly: Apply the sealer in a thin, even coat.
• Let the sealer dry completely: Before using the shower, let the sealer dry completely according to the manufacturer’s instructions.

Section 6: Troubleshooting Common Issues

Even with the best preparation and execution, things can sometimes go wrong during the regrouting process.

Here are a few common issues and how to fix them:

• Grout cracking or shrinking: This can be caused by using the wrong type of grout, mixing the grout incorrectly, or applying the grout in too thick of a layer.
  
  To fix this, remove the cracked or shrunken grout and reapply new grout, making sure to follow the manufacturer’s instructions carefully.
• Color inconsistencies: This can be caused by using different batches of grout, or by not mixing the grout thoroughly.
  
  To fix this, remove the grout with the inconsistent color and reapply new grout, making sure to use the same batch and mix it thoroughly.
• Difficulty cleaning off excess grout: This can be caused by letting the grout dry for too long before cleaning it off, or by using the wrong type of sponge.
  
  To fix this, try using a grout haze remover, which is a chemical solution that is designed to dissolve dried grout.
